Fix Windows handles leak

Fixes thread and process handles leak when running and killing project
from editor (caused by a missing CloseHandle call) plus a potential leak
when calling OS_Windows::execute with p_blocking and !r_pipe.

The leak could be easily observed with a Handles counter in Task Manager
(or Performance Monitor) for the Godot editor process.
